To'all whom it may concern:

Be it known that I, SAMUEL S. GAY, a citizen of the United States, residing at Sedro W'oolley, in the county of Skagit, State of Washington, have invented a new and useful Rail-Joint; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved rail joint, and an object'of the invention is to provide a device of this nature consisting of a dove-tailed joint having means to prevent one or the other of the joined adjacent rails from moving downwardly in advance of the other, thereby avoiding a shearing action upon the key connecting means which join the adjacent rail sections.

Another object of the invention is the provision of a key elongated or elliptical in cross section, to prevent the key from gradually rotating, which, if capable of gradually rotating, would eventually permit the lock 25 ing member of the key to fall out or dislodge :from the key.

in practical fields the details of constrnction may necessitate alterations, falling withinthe scope of what is claimed.

The invention comprises further features and combination of parts, as hereinafter set forth, shown in the drawings and claimed. In the drawings: Figure 1 is a plan View of a section of a pair of rails, showing the improved joint as applied to the adjacent ends of two sections of each rail, Fig. 2 is an enlarged detail perspective view illustrating the structure of the rail joint connecting the adjacent ends of two rail sections,showing the parts of the joint :(llS assembled.

Referring more especially to the drawings, 1 and 2 designate the adjacent sections of each rail, and as shown in Fig. 2 the base of the rail section 2 is cut away as shown at 3. The tread and the web of the rail sec- 8 is of the usual thickness.

rail section 2, thickened, formed vertically therein. The Web of the rail section 1 is provided with a thickened portion 8. However, from c to h: the web In other words, upon both sides of the web of the rail section 1, the thickened portion '8" of the Web terminates at (2, thereby cansii the iorma tion of the shoulders S which the which web is considerably end faces 8 engage or abut, when the web from a to 5 the section it enters the bifurcation The trend 8 of the rail section 1 is cut away as shown at 9 upon both sides, and the opposite faces of the tread where it is cut away are beveled or inclined downwardly and toward each other to a point indicated l1, so that said opposite inclined faces 12 may engage the adjacent correspondingly inclined faces 5 of the upper adjacent portions of he arms 6, to as sist in preventing the rail i from moving downwardly, and from moving upwardly. portion beyond the l cl C1 the rail section l. r: tion t, the lower e upon the t se of the r Jill 0f the rail a movement of in parts 12 section 2 and prevents apt the rail section ii The er and 12 and the en; .iciinerl faces 5 and 12 also prevent oravoid a. shear 5; action on the key 13. which may be received in the openings 7. The web E! of the rail sec-- tion 1 is providedtwith an opening '3'", cor responding in chose. to openings '2, and designed to regisicr with the openinqs 'i when the Web 8 re eived i i e hilarcation 4:. The key 13 has a head T at one end and a rectangu ar opening l? extending ly oi the other end, which opening is designed to receive the wedge member 18. The key 13 is made elongated or elliptical in cross section to correspondingly it the openings 7 and Hand to prevent the key 13 from turning. The wedge member 18 is designed to. be driven down into the opening 17, thereby drawing the arms 6 tight against the inclined faces 12and against the web 8 The Wedge member 155 has an opening 26 in its lower end rec the cotter pin 21, to prevent upward dispiacemento t wedge the so that the bifurcation 4: may be rail 1 section 2 is formed with a recess 22, to permit the wedge 18 to enter the rectangular opening 17 of said key.

The invention having been set forth,what is claimed as new and useful is:

1. In combination, a pair of adjoining rail sections. one of the rail sections having its base cut away so that the base of the other rail section may be received in the cut away portion, the rail section having the cut away portion having its web thickened and being provided with a vertical bifurcation which also extends upwardly through the tread, the upper portions of the adjacent faces of the bifurcation being inclined or beveled downwardly toward each ether, the other rail section having a thickened web, which, toward the end of the rail section is cut away to leave the-usual thickness of web to enter the bifurcation in the other rail section, the tread above said usual thickness of web being cut away, the opposite faces of which cut away portion being inclined downwardly to engage the inclined faces of said bifurcation, to assist in preventing movement of the rail sections relative to each other, the lower edges of the arms formed by said bifurcation engaging the base of the rail section with its tread cut away to assist in preventing movement of the rail sections vertically relative to each other, the webs of both rail sections having registering elongated shaped openings, and means engaging said openm to hold the sections connected.

2. In combination, a pair of adjoining rail. sections, one of the rail sections having its base cut away so that the base of the other rail section may be received in the cut away portion, the rail section having the cut away menace toward the end of the rail section is cut away to leave the usual thickness of web to enter the bifurcation in the other rail section, the tread above said usual thickness of web being cut away, the opposite faces of which cut away portion being inclined downwardly to engage the inclined faces of said bifurcation, to assist in preventing movement of the rail sections relative to each other, the lower edges of the arms formed by said bifurcations engaging the base of the rail section with its tread cut away to assist in preventing movement of the rail sections vertically relative to each other, the webs of both rail sections having registering elongated. shaped openings, and means engaging said openings to hold the sections connected, said means comprising akey, elongated in cross section to correspondingly lit said openings and having a head at one end and a rectangular opening at the other end, a wedge to engage said opening to hold the key in place, and a cotter pin passing transversely of the lower end of the wedge to hold the wedge in position.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
